评估增强与标准三维培训模型在腹腔镜技能中的功效：新手医学生的随机对照试验

该研究的目的是确定与新手医学生的标准3D Lappass培训模型相比，使用3D增强训练模型，使用3D增强培训模型，腹腔镜技能的获取是否会出色。 We hypothesized that adopting low-fidelity, 3D-enhanced training models in the 2D visual modality may expedite adaptation to monocular cues related to depth perception, enhancing performance.A prospective, single-center, 2-arm, randomized controlled trial with participants randomized equally into either 3D-enhanced or standard 3D group (allocation ratio 1:1, block sizes 2 and 4) performing 2 standardized laparoscopic任务：（1）马球抓握和操纵以及（2）体内缝合。使用腹腔镜技能（目标）工具，完成时间和错误数量的全球手术评估进行评估，并在基线，临时和培训后进行评估。一项研究后的调查测量了参与者感知到的信心和表现（ID：NCT06184854）。巴特斯癌症研究所，英国伦敦皇后大学玛丽玛丽大学。六十五名医学生，所有的腹腔镜手术的新手都均纳入了腹腔镜手术，并在每个小组中均可完成31个参与者。与两项任务中的基线相比，两组的训练后训练后表现明显优于（内部比较，p <0.017）。在组间比较中，在所有两项任务的所有比较中，3D增强组在统计学上的目标得分参数和深度感知域在统计学上显着改善（p <0.05）。但是，时间的改进和误差也有利于3D增强组，而没有达到统计显着性。在研究后的调查中，3D增强组报告说，仅缝合任务中的训练后信心和表现明显更高（p <0.05）。与标准3D Lappass模型相比，3D增强训练模型的使用导致了在2个任务中对新手进行出色的腹腔镜技能习惯。因此，将3D增强模型与标准3D Lappass模型一起纳入腹腔镜训练课程可以补充学习。进一步的工作应以基于能力的终点为重点。

The aim of the study was to determine if laparoscopic skills acquisition will be superior with the use of 3D-enhanced training models with increased dimensionality and spatial complexity compared to standard 3D LapPass training models in novice medical students. We hypothesized that adopting low-fidelity, 3D-enhanced training models in the 2D visual modality may expedite adaptation to monocular cues related to depth perception, enhancing performance.A prospective, single-center, 2-arm, randomized controlled trial with participants randomized equally into either 3D-enhanced or standard 3D group (allocation ratio 1:1, block sizes 2 and 4) performing 2 standardized laparoscopic tasks: (1) polo grasping and manipulation and (2) intracorporeal suturing. Performance was assessed using the Global Operative Assessment of Laparoscopic Skills (GOALS) tool, completion time, and number of errors, with evaluations at baseline, interim, and post-training for each task. A post-study survey measured participant-perceived confidence and performance (ID: NCT06184854).Barts Cancer Institute, Queen Mary University of London, UK.Sixty-five medical students, all novices in laparoscopic surgery, were enrolled, with 3 dropouts.Thirty-one participants in each group completed the study with homogeneity regarding demographic data (p > 0.05). Both groups had significantly superior performance post-training compared to baseline in the 2 tasks (intragroup comparison, p < 0.017). In the intergroup comparison, the 3D-enhanced group had statistically significantly greater improvements in the GOALS score parameter and depth perception domain across all comparisons for both tasks (p < 0.05). Time improvement and error reduction also favored the 3D-enhanced group, however, without reaching statistical significance. In the post-study survey, the 3D-enhanced group reported significantly greater perceived post-training confidence and performance in the suturing task alone (p < 0.05).The use of 3D-enhanced training models resulted in superior laparoscopic skills acquisition for novices in 2 tasks compared to standard 3D LapPass models. Therefore, incorporating 3D-enhanced models into laparoscopic training curricula alongside standard 3D LapPass models can supplement learning. Further work should focus on long-term efficacy with a competency-based endpoint.
